We combine the six high-resolution Aquarius dark matter simulations with a semi-analytic galaxy formation model to investigate the properties of the satellites of Milky Way-like galaxies. We find good correspondence with the observed luminosity function, luminosity-metallicity relation and radial distribution of the Milky Way satellites. The star formation histories of the dwarf galaxies in our model vary widely, in accordance with what is seen observationally. Some systems are dominated by old… Expand
Probing baryonic processes and gastrophysics in the formation of the Milky Way dwarf satellites: I. metallicity distribution properties
In this paper, we study the chemical properties of the stars in the dwarf satellites around the MW-like host galaxies, and explore the possible effects of several baryonic processes, includingExpand
Erratum: elemental abundances in Milky Way-like galaxies from a hierarchical galaxy formation model
We develop a new method to account for the finite lifetimes of stars and trace individual abundances within a semi-analytic model of galaxy formation. At variance with previous methods, based on theExpand
Can cosmological simulations capture the diverse satellite populations of observed Milky Way analogues?
The recent advent of deep observational surveys of local Milky Way `analogues' and their satellite populations allows us to place the Milky Way in a broader cosmological context and to test models ofExpand
The Orbital Ellipticity of Satellite Galaxies and the Mass of the Milky Way
We use simulations of Milky Way-sized dark matter haloes from the Aquarius Project to investigate the orbits of substructure haloes likely, according to a semi-analytic galaxy formation model, toExpand
One of the strongest predictions of theCDM cosmological model is the presence of dark satellites orbiting all types of galaxies. We focus here on the dynamical effects of such satellites on diskyExpand
Building blocks of the Milky Way's accreted spheroid
In the $\Lambda$CDM model of structure formation, a stellar spheroid grows by the assembly of smaller galaxies, the so-called building blocks. Combining the Munich-Groningen semi-analytical model ofExpand
Many properties of the Milky Way's (MW) dark matter halo, including its mass-assembly history, concentration, and subhalo population, remain poorly constrained. We explore the connection betweenExpand
Matching the dark matter profiles of dSph galaxies with those of simulated satellites: a two parameter comparison
We compare the dark matter halos' structural parameters derived for four Milky Way dwarf spheroidal galaxies to those of subhalos found in cosmological $N$-body simulations. We confirm that estimatesExpand
Evolution of dwarf galaxy observable parameters
We present a semi-analytic model of isolated dwarf galaxy evolution and use it to study the build-up of observed correlations between dwarf galaxy properties. We analyse the evolution using modelsExpand
Semi-analytic modelling of the europium production by neutron star mergers in the halo of the Milky Way
Neutron star mergers (NSM) are likely to be the main production sites for the rapid (r-) neutron capture process elements. We study the r-process enrichment of the stellar halo of the Milky WayExpand


On the Nature of the Milky Way satellites
We combine a series of high-resolution simulations with semi-analytical galaxy formation models to follow the evolution of a system resembling the Milky Way and its satellites. The semi-analyticalExpand
The population of Milky Way satellites in the LambdaCDM cosmology
We present a model for the satellites of the Milky Way in which galaxy formation is followed using semi-analytic techniques applied to the six high-resolution N-body simulations of galactic halos ofExpand
The origin of failed subhaloes and the common mass scale of the Milky Way satellite galaxies
We study the formation histories and present-day structure of satellite galaxies formed in a high-resolution hydrodynamic simulation of a Milky Way like galaxy. The simulated satellites span nearlyExpand
On the common mass scale of the Milky Way satellites
We use a hybrid approach that combines high-resolution simulations of the formation of a Milky Way-like halo with a semi-analytic model of galaxy formation to study the mass content of dwarf galaxiesExpand
From dwarf spheroidals to cD galaxies: simulating the galaxy population in a ΛCDM cosmology
We have updated and extended our semi-analytic galaxy formation modelling capabilities and applied them simultaneously to the stored halo/subhalo merger trees of the Millennium and Millennium-IIExpand
Luminosity function and radial distribution of Milky Way satellites in a ΛCDM Universe
We study the luminosity function (LF) and the radial distribution of satellite galaxies within Milky Way (MW) sized haloes as predicted in cold dark matter based models of galaxy formation, makingExpand
The Galaxy and its stellar halo: insights on their formation from a hybrid cosmological approach
We use a series of high-resolution simulations of a 'Milky Way' halo coupled to semi-analytic methods to study the formation of our own Galaxy and its stellar halo. The physical properties of ourExpand
Probing the epoch of reionization with Milky Way satellites
While the connection between high-redshift star formation and the local Universe has recently been used to understand the observed population of faint dwarf galaxies in the Milky Way (MW) halo, weExpand
A new view of the dwarf spheroidal satellites of the Milky Way from VLT flames: Where are the very metal-poor stars?
As part of the Dwarf galaxies Abundances and Radial-velocities Team (DART) program, we have measured the metallicities of a large sample of stars in four nearby dwarf spheroidal galaxies (dSph's):Expand
On the Distribution of Orbital Poles of Milky Way Satellites
In numerous studies of the outer Galactic halo some evidence for accretion has been found. If the outer halo did form in part or wholly through merger events, we might expect to find coherent streamsExpand
